摘要
应用物种丰富度和物种多样性指数及群落均匀度等指标对浙江省天台山常绿阔叶林次生演替序列物种多样性进行研究。结果表明 :天台山次生森林从针叶林到针阔混交林到常绿阔叶林的演替过程中 ,物种多样性呈先变大后变小的趋势。在群落的垂直结构中 ,次生演替序列 3种群落类型的物种丰富度和物种多样性指数的大小顺序均为灌木层 (包括幼苗及幼树 ) >乔木层 >草本层。在 3种群落类型中 ,木本植物的物种多样性均大于草本植物。表 4参
Studies of the secondary successional species diversity of the evergreen broad leaved forests at Mount Taintai of Zhejiang Province were conducted by using such index as species richness,species diversity and community evenness.The result shows that the species diversity of the secondary forests at Mount Tiantai has the tendency of developing from big to small in the course of succession from the needle leaved forest,needle leaved and broad leaf mixed forest to the evergreen broad leaved forest.In the communitys vertical structure,the order according to the bigness of the species richness and the species diversity index of the 3 secondary successional communities is the shrub layer(including seedlings)>tree layer>herb layer.All the species diversity of the woody plant is bigger than that of the herb layer among the 3 communities.
